FRANCIS C. OSBORN, OF DETROIT, MICHIGAN, ASSIGNOR TO STANDARD COMPUTING SCALE COMPANY, OF DETROIT, MICHIGAN, A CORPORATION OF MICHIGAN.

COMPUTING-SCALE.

To all whom it may concern:

Be it known that I, FRANCIS C. OSBORN, a citizen of the United States, and a resident of Detroit, in the county of Wayne and State of Michigan, have invented a new and Improved Computing-Scale, of which the following is a specification.

This invention relates to improvements in computing scales and its object is to provide a scale of great stiffness and steadiness which shall be readily changeable from platform to scoop weighing.

This invention consists in a noval plat form supporting frame and means for mounting the same.

It further consists in novel means for supportingthe scoop from the supporting frame.

It further consists in a novel adjusting poise and the means for supporting the same.

It further consists in a novel construction of beam.

It further consists in the novel details of construction illustrated in the drawings, described in the specification and pointed out in the claims.

In the accompanying drawings, Figure 1 is a front view of the improved scale. Fig. 2 is a plan of the platform supporting frame and the levers connected thereto. Fig. 3 is a vertical sectional view of the base of the scale taken on the line AB of Fig. 2. Fig. 4 is a plan of the base on a small scale. Fig. 5 is a central longitudinal cross-section of the frame. Fig. 6 is a transverse section of the same on the line CD of Fig. 5. Figs. 7 8 and 9 are details.

Similar reference characters refer to like parts throughout the several views.

The scale shown in the drawings comprises a base 1, an upright frame 2, a tarebeam 3, with main poise 4, slidable poise 5 and adjusting poise 6, the computing panel 7 suitably supported, levers, and connections for the same.

Within the base 1 are four lugs 8 which support the screw-eyes 9 from which are suspended the loops 10 and 11 that carry the four bearing blocks 12 and 13. A lever 14 has down turned knife-edges 15 that rest on the blocks 12, upwardly turned knife-edges 16 that support the blocks 17 an upwardly turned knife-edge 18 that supports the block 19, and an outwardly extending arm 20 hav Specification of Letters Patent.

ing a pin 21 that engages the hook at the lower end of the rod 22.

A lever 23 has down turned knife-edges 24 that rest on the blocks 13, upwardly turned knife-edges 25 that support the bearing blocks 26, and an arm 27 having a knifeedge 28 at its outer end. This knife-edge rests on the block 29 that is connected to the block 19 by means of the link 30.

A. generally rectangular platform-supporting frame 32 is provided with pairs of lugs 34 at its front edge which carry pins 35. These pins pass through links 33 that connect to the bearing blocks 17 At its rear edge the frame has depressions 36 in which are mounted the pins 37 that pass through links 38 connected to the blocks 26. Posts 43 connect to this frame, and at their upper ends carry the platform 44. A scoop support on the end of the arm 42 is so mounted that the scoop may be over or at one side of the platform, the support being in either of the positions shown in solid and dotted lines in Fig. 4. The arm may be rigid or swiveled, it may be mounted on the supporting frame or directly on the platform or any extension thereof as at the point 70 (Fig. 4). I prefer to pivot the down turned end 41 of this arm 42 in the sleeve 40 on the arm 39 of the supporting frame 32. The parts may be so proportioned that the arm 42 will swing freely over the platform until the scoop is loaded when the holder will spring down and rest on the platform, but the holder can be made strong enough to swing freely with a loaded scoop.

The main frame 2 is formed with a hori- Zontal slotted top on which rest the bearing blocks 50 (Figs. 5 and 6). Between the legs is a shelf 51 for weights. Caps 52 are secured to cover these blocks 50 and the main knife-edges 53 of the tare beam. An arm 54, projecting down from the tare beam Fig. 7 carries the rod 55, on which is screwed the adjustable poise 6, the screw 56 looking the poise in position. The poise is mounted eccentrically to the rod and turning the poise serves to adjust the scale. It will be noticed that this rod extends down directly below the knife-edges 53. The rod 55 extends down through the slot in the top of the frame 2 and through a slot in the shelf 51, the shelf serving as a guard for the poise.

The rod 22 hooks into the link 57 which carries the usual bearing blocks 58 at its upper end, which blocks rest on the knifeedges 59 of the tare-beam. The arms 60 and 61 project upward from the tare beam and carry screws 62 (Fig. 8) that engage in the ends 63 of the rectangular frame of the computing panel. This panel may be graduated for weight divisions and monetary divisions in any manner desired but this graduation forms no part of this present invention. The poise 65 is employed in the manner usual to computing scales. The end members 63 and side members 66 of the rectangular frame of the computing panel are made integral or are rigidly connected, and as a result, when the arms 60 and 61 are drawn up by means of the screws 62 so as to spring them slightly, the panel frame together with the tare beam 3 forms a rigid construction permitting a great reduction in dimensions of the part-s over those now in use. The construction is such however that the panel is not prevented from being turned, the friction of the heads of the screws 62 holding it in any position towhich it is turned.

Having now explained my improvements, what I claim as new and desire to secure by Letters Patent is 1. In a scale, the combination of a frame, bearing blocks carried thereby, a scale beam provided with knife-edges adapted to rest on said blocks, a rod depending from said beam, and an eccentric adjusting poise pivotally mounted on said rod.

2. In a scale, the combination of a frame, bearing blocks carried thereby, a scale beam provided with knife-edges adapted to rest on said blocks, a rod depending from said beam, and a disk eccentrically' and pivotally mounted on the rod.

3. In a scale, the combination of a frame, bearing blocks carried thereby, a scale beam provided with knife-edges adapted to rest on said blocks, a vertical rod extending from said beam under the line of said knife-edges, and an eccentric disk pivotally mounted on said rod.

4. In a scale, the combination of. a frame, bearing blocks carried. thereby, a scale beam provided with knife-edges adapted to rest on said blocks, a rod depending from said beam under the line of said knife-edges, a disk eccentrically and pivotally mounted on the end of said rod to form an adjusting poise,

and a shield mounted on said frame over said disk.

5. In a scale, the combination of a base, frame, beam and platform, of a platform supporting frame, and an arm pivotally connected to said frame and provided with scoop supporting means at its outer end, said arm adapted to be swung over the platform so the scoop may bear its weight on the platform.

6. In a scale, the combination of a base, frame, beam and platform, of a platform supporting frame connecting to said beam and having a rearwardly extending arm provided with a sleeve, and a rod having a down-turned end swiveled in said sleeve and having scoop retaining arms at its free end, the free end of the arm swinging above the platform so the scoop may bear its weight thereon.

7. In a scale, the combination of a base, a frame, a beam mounted on said frame, scale levers mounted in said base and connected to said beam, a platform supporting frame mounted beneath said levers, supporting links connected to said. supporting frame and to said levers, posts extending upwardly from said supporting frame, and a platform resting on said posts.

8. In a scale, the combination of a base, a frame, a beam mounted on said frame, scale levers mounted in said base and connected to said beam, a platform supporting frame mounted beneath said levers, supporting links connected to said supporting frame and to said levers, posts extending upwardly from said supporting frame, a platform resting on said posts, and a scoop support pivotally mounted on said supporting frame.

9. In a scale, the combination of a frame, bearing blocks carried thereby, a scale beam provided with knife-edges adapted to rest on said blocks, a rod extending down from said beam, a disk eccentrically mounted on said rod to form an adjusting poise, and a weight shelf supported by said frame over said disk, adapted to form a shield for the same- In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
